Pay staff better considering the amount of abuse they put up with from customers. Remove toxic managers or have better processes in place for staff to report emotional bullying / harrasment from management.
I would listen to my staff, treat them like actual humans not robots and just a number.
I will pay more attantion to the staff requests
Hire more staff so we can deliver customers better service especially during the weekends. And add a cafe because loads of customers kept asking for that.
